Google Data APIs client libraries are available to help you write client applications that access your favorite API.

For each language, the client library provides tools and an abstraction layer, letting you construct queries and use response data without having to create HTTP requests or process HTTP responses by hand. Each client library provides classes that correspond to the elements and data types that the API uses.

For more information on how to use the client libraries, visit the API Directory and click through to the documentation for a specific API.

Client Libraries Provided by Google

The following client libraries are written and supported by Google. Most are hosted on Google Code, so you can view the open-source code (via svn), browse feature requests, view FAQ's, and file bug reports.
